title: Blood-spot 17-hydroxyprogesterone daily profiles in infants with congenital adrenal hyperplasia.
abstract: To define the optimum blood levels of 17-hydroxyprogesterone, the hormonal effects of glucocorticoid treatment were studied during the neonatal period and infancy in 20 patients with 21-hydroxylase deficiency. Repeated daily profiles of blood spot 17-hydroxyprogesterone were used to monitor therapy and these data were related to serum concentrations of testosterone. A wide fluctuation of blood 17-hydroxyprogesterone levels was observed in patients with a mean daily value higher than 150 nmol/l indicating poor control. Serum testosterone levels decreased into normal range in female patients with blood-spot 17-hydroxy-progesterone levels between 50 and 150 nmol/l. Daily profiles with mean values less than 50 nmol/l showed low magnitude of circadian variation suggesting overtreatment. We conclude that the daily profile of blood-spot 17-hydroxyprogesterone is a practical alternative in hormonal monitoring of infants treated for congenital adrenal hyperplasia.
